Fig. 10 is a similar section taken substantially on line Ill-I8 of Fig.8,

Fig. 11 is a view similar to Fig. 8 with both sashes swung inwardly.

Fig. 12 is an elevation of a modication of the invention;

Fig. 13 is a cross setcion on line I3|3 of Fig. 12; and

Fig. 14 is an enlarged section of a portion of the structure of Fig. 13.

Referring to the drawings, the numeral I designates a top window framemember suitably connetced to side frame members and I2, the lower endsof which are suitably secured to the customary sill I3, under which theusual molding I4 may be provided.

As will be noted from Fig. 2, the sill I3 preferably has a portion Iwhich may be integral therewith, that extends through the outer sheetingI6 of the dwelling in which the window is mounted and may rest on one ofthe suppotring elements of the dwelling, such as a 2 by 4, I1. Theportion I5 of the sill tapers as at |8 throughout the greater portion ofits width and has an increased taper at I9, the purpose of which will beexplained hereinafter. Adjacent the lower edge of the top frame memberIU, a horizontal supporting member 20 is suitably secured and the latteris also suitably secured to the outer sheeting I6.

A vertical support 2| (see Fig. 4, 6, `8 and ll) extends from the member20 downwardly to the sill and is secured at its front end to framemember I I adjacent the inner edge of the latter, while its rear end issecured to a ller member 22 which in turn is secured to the wallsheeting I6. A similar support 23 is secured between frame member I2 anda second ller member |22, and extends between the sill and support 2U.

Secured to the inner faces of support 2| and filler members 22 and |22is a vertical frame member 24 that extends from the sill to the support20. Member 24 is generally substantially rectangular in cross-sectionwith a portion cut out and rounded as indicated at 25. A vertical framemember 26, similar in cross-section and length to member 24, is securedto support 23 and filler |22, and has a portion cut out and rounded asat 21.

Co-operating with frame members 24 and 26 for both vertical and swingingmovement with respect thereto, is an upper sash member, indicated as awhole by the numeral 28, having upper and lower rails 29 and 35, andside rails 3| and 32, all of which enclose va pane of glass 33. Asshown, a channeled guide and hinge member 34, generally arcuate incross-section, extends from the sill to the support 20 and has aflattened p0rtion 35 usually secured to and embedded in the front faceof frame member 24, being secured to the latter by counter-sunk screws36, or the like. Any suitable guide and hinge member, such as a pair ofvertically spaced guide and hinge elements 31, is secured to the siderail 3| adjacent the upper and lower ends of the latter. Elements 31 aregenerally annular in cross-section and have Ka flattened extension 38which usually is embedded in the side face of rail 3| that is adjacentto the frame member 24, being secured plementary to and co-operates withthe rounded portion 25 of the frame member 24 to assist in providing aseal when the upper sash member 28 is in its closed position, asindicated in Figs. 4 and 8. The Iarrangement is such that the hingeelements 31 fit within the channeled member 34 and may either slidevertically or pivot therein, so that the upper sash may be movedvertically or swung inwardly from its closed position and then outwardlyto its closed position.

Suitable lock means, which also may provide a guide for the oppositeside rail 32, are provided for thev upper sash member 28. These meansmay include a channeled guide member 4|, also generally arcuate incross-section like the member 34, that extends from the sill to thesupport 28 and has a attened portion 42 usually embedded in the frontface of the frame member 26, being secured to the latter by countersunkscrews 43, or the like. In its lower portion, guide member 4| isprovided with one or more, in this instance two elongated spacedopenings 44, which open to the front of the member 4| or toward theinterior of the dwelling. A pair of guide and locking elements 45 aresecured to spaced portions of the side rail 32 adjacent the upper andlower ends of the latter. The spacing of the elements 45 is equal to thespacing of the openings 44, but the latter are slightly longer than theelements 45. Locking elements 45 are generally annular in cross-sectionwith their ends tapered inwardly for streamlining, and have a flattenedextension 46 (Fig. 5) which usually is embedded in the side face of rail32 that is adjacent to the frame member 26, being fastened to rail 32 bycounter-sunk screws 41, or the like. Rail 32 has a rounded portion 48that co-operates with the rounded portion 25 of frame member 26 toassist in providing a seal when the upper sash member 28 is in itsclosed position. The arrangement is such that the locking elements 45 twithin the channeled member 4| and may slide vertically therein, butwhen the elements 45 are in alignment with the openings' 44, theseelements may be swung inwardly out of engagement with guide member 4| bywhich movement the upper sash member also is moved pivotally about theguide 34.

Thus, the upper sash 28 may be moved vertically of the window frame withthe hinge elements 31 and the locking elements 45 acting as guideswithin the channeled members 34 and 4|, respectively, while this sashmay be swung inwardly only when in a lowered position with the lockingelements 45 in alignment with the openings 44. However, once released,the sash 28 may be moved to any desired vertical position and still beswung approximately from its closed position.

Inwardly of frame member 24 and secured to the front face thereof so asto cover the attened portion 35 of channeled member 34, usually there isa vertical spacing member 49 that extends from the sill to the support20. Member 49 may also be secured to support 2| and is preferably of athickness about equal .to the outside diameter of channeled member 34.Secured to the inner faces of support 2| and spacer 49 is a smallerwidth vertical frame 50, extending from the sill to the top support 20,being generally rectangular in cross-section except that it is cut outand rounded as at 5|.

Secured to the front face of frame member 26 so as to cover theflattened portion 42 of the channeled member 4|, and also to thevertical support 23, usually is a vertical spacing member 52, similar tomember 49 and coextensive with the latter, except that the member 52 ispreferably not as wide as member A119 to accommodate the guide 4| whichis positioned, usually, to the side of the upper sash member. A verticalframe member 53 is secured to the inner faces of support 23 and spacer52, and member 53 is of the same general shape and length as framemember 50, except that the former is somewhat thicker than the latter,which provides space into which the sash 28 may swing, and has a portioncut out and rounded as at 55.

Co-operating with frame members 53 and 53 for both vertical and swingingmovement with respect thereto, is a lower sash member, indicated as awhole by the numeral 56, having upper and lower rails 51 and 58, andside rails 59 and 60, all of which enclose a pane of glass 5|. Achanneled guide member 62, similar in all respects to guide member 31S,extends from the sill to the support and has a flattened portion 63,usually secured to the front face of frame member 55, being fastened tothe latter by counter-sunk screws 54, or the like. A pair of spacedguide and hinge elements 55, similar in all respects to the elements 31,are secured to the side rail 59 adjacent the upper and lower ends of thelatter. Hinge elements 65 have a flattened extension 68, as shown inFig. 8, which is shown embedded in the side face of rail 59 that isadjacent to frame member 59, being fastened to said rail by countersunkscrews 6l, or the like. ySide rail 59 also has a rounded portion 68 thatco-operates with the rounded portion 5| of frame member 5i! to assist inproviding a seal when the lower sash member 56 is in closed position, asindicated in Figs. 6 and 8. The arrangement is similar to thearrangement previously described for the upper sash 28, whereby hingeelements 65 fit within the channeled member 62, so that the lower sash55 may be moved vertically at any time and also be pivotally moved aboutthe longitudinal axis of the elements 65.

A channeled guide member B9, similar in all respects to guide member 4|,and best shown in Figs. 4 and 5, extends from the sill to the supportand has a attened portion 'l0 that is usually embedded in the front faceof the frame member 53, being fastened to the latter by counter-sunkscrews ll, or the like. In its lower portion, guide member 69 isprovided with elongated spaced openings '2 (see Figs. 1 and 10), similarin all respects to the openings lill and parallel therewith. A pair ofspaced guide and locking elements '53, usually similar in all respectsto locking elements 5, are secured to the side rail 59 adjacent theupper and lower ends of the latter, and have a flattened extension 'i4that is embedded in the side face of rail 60 that is adjacent to framemember 53, being secured to rail 60 by counter-sunk screws l5, or thelike. Rail 6@ has a rounded portion l5 that co-operates with the roundedportion 55 of frame member 53 to assist in providing a seal when thelower sash member 56 is in closed position. The arrangement is againsimilal1 to that described in connection with the upper sash member 2B,whereby the hinge elements 55 and the locking elements 'i3 act as guideswithin the channeled members 52 and 69, respectively, during Verticalmovement of the lower sash member 53, while the latter may be swunginwardly only when the locking elements 13 are in alignment with theopenings 12.

A small spacer member v'l1 extends from the.

sill to the support 20, and is secured to the adjacent faces of support2| and side frame member i in position to cover and conceal theiiattened' portion 63 of channeled member 62. A similar spacer 'I8 issecured to support 23 and side frame member I2` to cover and conceal theflattened portion l0 of channeled member 69.

It will be observed more particularly from Figs. 1 and 8 that the glasspanes 33 and 5| are in proper alignment and parallel when the upper andlower sashes are in closed position. The meeting rails, 3! of the uppersash and 5l of the lower, as shown in Fig. 2, have their meeting facesinclined as at 'I9 and 80, and slightly overlapping as at 8|, to providea weather-tightseal between the sashes. A conventional locking means 82(Fig. 1) may be provided to lock th sashes in closed position.

A conventional sash balance is provided for each of the sashes 28 and55. The balancesv shown are indicated as a whole by the numeral 33, andare known as the Caldwell type of balance. These balances are availableon the market and their operation is understood by those familiar withthis art, so that a detailed description of its parts and operation isnot believed to be necessary. As indicated in Fig. 3, each balanceextends through an opening 84 in the support 29, and its base plate 85is secured in the latter support by screws 85. Its cable 8l, usuallymetallic is spring controlled, and in the balance shown in Fig. 3, thiscable passes through an opening 58 in the base plate 85 and usually hasits lower end extending into and secured to the upper hinge element 35of the lower sash 58, as indicated in Fig. 9. The cable 8l of the otherbalance may be similarly connected to the upper hinge element 3l of theupper sash member 28, as indicated in Figs. 1 and 2. It should be notedthat the cables for their complete length extending from the balancesare completely enclosed in the members 313 and 52 which are iixedlysecured in the window frame so that the cables are never exposed.

As shown in Figs. 1 and 2, safety blocks 95 are secured to the lowersurface of support 25 in vertical alignment with the upper rail 51 ofthe lower sash 55. This arrangement provides abutments against which thelower sash may strike in its upward vertical movement which will preventthe latching mechanism 82 from contacting support 2i! and being damagedthereby.

A rubber or rubber composition or other conventional sealing strip 9|(Fig. 2) is embedded in the upper end of rail 29 of the upper sash to'insure a weather-tight seal when the upper sash is locked in closedposition. A weather-tight seal is obtained at the bottom of the lowersash member by beveling the lower front portion of bottom rail 58, asindicated at 92, so that the bevel 92 co-operates with the beveledportion |9 of sill i3, while a less beveled portion 93 on rail 5Sco-operates with the beveled portion I8 on the sill. Thus, a tight fitis assured between the sill and the lower sash member.

l'n the operation of the sashes, their closed and locked position isindicated in Figs. 1 and 2, and after the latching mechanism S2 isreleased, either sash may be moved vertically up and down in the samemanner that ordinary double hung sashes may be operated. During theirvertical movement these sashes are guided by the oppositely disposedhinge and locking elements 7 moving within. the channeled members thatextend for the full height of the window opening, and the sash balanceswill permit raising or lowering of the sashes to the desired extent.

In order to swing the lower sash inwardly like a easement window it isonly necessary to align the locking elements 13 with the opening 12 (seeFig. 9) and the lower sash may be swung inwardly as indicated in Fig.1.1. If the lower sash is down as in Fig. 1 when it is desired to swingit open, it is necessary to raise the sash a little in order to alignelements 'I3 properly with the openings 12.

When it is desired to swing the upper sash inwardly, it is necessary tolower the upper sash until its locking elements 45 are in properalignment with openings 44. If the lower sash has then been swung open,it is possible to swing the upper sash inwardly also, as indicated inFig. 11. It will be observed that the upper sash cannot be swunginwardly until the lower sash has first been swung inwardly.

It will be realized that any size or number of the guide and hingeelements 31 and 65 may be provided in the window construction of theinvention. Likewise, the guide and locking members 45 and 13 provided onthe opposite side of the window sash of the invention can be of anydesired size and number inasmuch as the openings 44 and 12 are formed ofcomplementary size and shape to the slides numbers 45 and 13 wherebythey may pass through such openings. Furthermore, the guide and lockingrails 4I and 69 that are secured to the window frame may be of anydesired cross section with the slides 45 and 13 then being formed of ashape substantially complementary to the cross sectional contour of therails with which such slides are engaged. It even would be possible inpractice of the invention to use entirely diierent type of lock means onthe releasable side of the window construction so as to retain it in aclosed position at any desired time. Such means might even comprise aconventional device such as a spring bolt which would be carried by eachof the window sashes and have keepers or receiving sockets providedtherefor on the sides of the frame. However, normally I prefer to usesome type of elongate guide means with which the free edges of thesashes 28 and 56 may be releasably engaged for vertical sliding movementso as to retain such windows in tight association with the window frameat all normal times.

Since the cables 81 which extend down from the balances 83 are receivedwithin the guide members 34 and 62, these cables are completely enclosedat all times. Such guide and hinge members are xedly secured to thewindow frame whereby it is relatively easy to clean around same and themovable cables do not provide any cleaning obstacle.

While in the drawings disclosed herein, the release points for both theupper and lower sashes are shown at the same vertical position, in someinstances it may be desirable to provide such release points at spacedvertical portions of the window frame. Also, the pivot and hinge devicecould be horizontally positioned in place of vertically positioned.

The principles of the invention are applicable to any type of windowconstruction and such window may be made from any desired material,either wood or metallic. Furthermore, the window construction issatisfactory for use with oriel windows, while it might also be usedwith a triple hung window where it is desired to have one or morewindows movable and pivotal with relation to the others. Furthermore, insome instances the window construction might even be used with merelyone window which has a vertical space into which it can be slid, whendesired to expose the window opening. Also the construction could beused with a window which has only limited vertical movement in itsassociated frame. It should be noted that, as indicated in Fig. 11 ofthe drawing, both sashes 28 and 56 can be swung through substantially90: degrees movement in opening same to expose the window openingcompletely. This feature is achieved by the provision of appreciablywider side frames for the upper sash 28 with relation to the side framesthat are used for the lower sash 56 and the differences in such width iscompensated for in the assembly by the guide rails 24 and 26 in relationto the guide rails 50 and 53 forming part of the window frame. Thesemembers are complementary to the side rails of the window sash and theirwidth diierences compensates for the differences in width of the windowsash members.

In some instances it might be desirable to combine the space strips 49and 52 with the associated frame strips 50 and 53, respectively, sinceitmay be preferable to form such members integral. Also, the spacerstrips 11 and 18 might even be made integral with the rest of the framemembers, when desired, only in such instancesv the arms 63 and 10 on thehinge locking members would then usually be made to extend along theouter surfaces of the window frame. Likewise the entire side members 24,49, 5D and 11 and corresponding members on the other side may possiblybe combined to form an integral side member for the window frame. Thisconstruction would then have the guide and hinge members be secured tothe exposed surface of the sides of the window frame.

It is believed to .be apparent that I have provided a novel windowconstruction which has all the advantages of a double hung window andalso has advantages over a easement window. The sashes may readily bereached for cleaning, painting, washing, etc., and can be positioned inany desired Avertical location for such action. Further, my windowconstruction is well adapted for use with storm windows or screens andfacilitates access to movement of same. In Figs. 2, 4, 6, 8 and 11, Ihave shown a storm window mounted in a storm sash 96 which is removablysecured to a frame 91 that is permanently mounted in the outer sheetingI6 of the dwelling. As will be noted from Fig. 11, the storm sash mayreadily be removed and replaced from inside the dwelling after thesashes 28 and 56 have been swung open.

Figs. 12, 13 and 14 of the drawings show a modification of the inventionwherein special means are illustrated for retaining the slide members onthe releasable edges of the window sashes in engagement with theirretaining channels even when such window sash is positioned at itsrelease point. This embodiment of the invention also illustrates asimpler type of vertical frame means which may be used in practice ofthe invention, but the apparatus disclosed, in general, is the same asthat of the previous embodiment of the invention. Fig. 13 best showsthat ller members IOI and |02 may be provided in the window frame andhave vertical supports |03 and I04 secured thereto in any conventionalmanner. The front edges of the vertical supports ID3 and I04 may haveconventional molding strips I65 and |06, respectively, associatedtherewith whereas any desired means (not shown) may be secured to the:filler members. Figs. 13 and 14 best show that a vertical frame memberlill and |018 respectively, is secured to each of the vertical supports|03 and |04 and extends substantially the width or depth thereof and theforward surfaces of such vertical frame members lill and HI8 areprovided with shoulders |09 and I il] and with curved surfaces |I Iv and|I2, respectively, similar to the other embodiment of the invention. Arelatively smal-l vertical frame member IIS and II4 is secured to thetransversely inner surfaces of each of the frame members lill' and |23,respectively, adjacent the outer portion thereof, that is, the portionadjacent the outside of the window frame of the invention. Anyconventional means, such as elongate bolts H5 and l la and shorter boltsIIS and IIEa may be used to secure the vertical frame members IiVI andi818 to the remainder of the frame whereas the small vertical framemembers II3 and lill may be secured in place in any desired manner.Bolts i5 also usually position a guide and hinge member IIl adjacent therear of the window frame, and bolts IIS a guide and hinge member H3adjacent the front oi the window frame, while bolts Iia position ananchoring and guide member or element IIS adjacent the rear of the otherside of the frame while a similar anchoring and guide element |22 ispositioned adjacent the front of the window frame by .bolts I ld.. Awindow sash, indicated generally by the numeral i2i, is provided forvertical sliding movement intermediate the guide and hinge member i i8and the anchoring and guide member IZB and a hinge element |22 issecured to one lateral margin oi the window sash I2! for this purpose.

Fig. 14 of the drawings best shows an important feature of the inventionwhich is that of providing a retainer lip |23 that is formed on theanchor and guide element at a release opening :'24 that is formedtherein. This anchoring and guide member IZB engages with a guideelement which is conventionally secured to a sill member i2E of thewindow sash i2 I. It should be noted that the retaining lip |23 adjacentthe base thereof is outwardly and arcuately curved to be in snugengagement with the guide member |25 and that the lip |23 extends upapproximately one third or" the diameter of the guide member 25 inengagement therewith whereas the outermost end of the lip 23 is curvedbackwardly upon itself, or outwardly with relation to the guide 25 to becompletely free from same. Thus the lip |23 is adapted to retain theguide |25 in engagement with the anchor and guide member I2!) even whenthe guide is positioned at the opening |24 but that a slight forceapplied to the window sash I2! at the free edge thereof will spring theguide member |25 out of engagement with the lip I 23. Likewise, whenengaging the guide with the lip |23, it can be temporarily iiattened, asindicated in dotted lines in Fig. 14 to engage the guide and lip. Thelip |23 normally is integral with the anchor and guide I2II and isformed of such material, usually metal, as to be resilient and permitengagement of the lip and the guide member |25, or disengagementthereof, at any desired time but normally retain the two in a givenrelation. A similar lip |2'I is also provided on the anchor and guidemember II9 at a release opening |28 formed therein.

In some instances, it may be desired to use another type of a retainermember, such as an overlying resilient clip, in association with therelease lli) openings formed in the guide and anchoring members of theinvention.

While usually not as desirable as the constructions illustrated herein,it is possible to form the hinge and guide elements carried on thewindow sashes, of such contour that they would engage with the outersurfaces of the hinge and anchor members rather than being receivedwithin the bores of such members, as shown.

Inner and outer in this specication and claims normally relates to thewindow and frame with relation to the house or other building with whichthe window and frame are associated.

While I have shown and described the preferred embodiment of myinvention, it will be apparent that the invention is not limitedthereto, and changes and modications may be made therein withoutdeparting from the spirit of the invention or from the scope of thesubjoined claims.
